按照《mongdb權威指南》當使用version 3.4.1版本的mongodb,其中使用batchInsert函數進行對students集合進行批量插入
db.students.batchInsert([{"classid" : 1, "age" : 20, "name" : "kobe"}, {"classid" : 1, "age" : 23, "name" : "nash"}, {"classid" : 2, "age" : 18, "name" : "james"}, {"classid" : 2, "age" : 19, "name" : "wade"}, {"classid" : 2, "age" : 19, "name" : "bosh"}, {"classid" : 2, "age" : 25, "name" : "allen"}, {"classid" : 1, "age" : 19, "name" : "howard"}, {"classid" : 1, "age" : 22, "name" : "paul" }, {"classid" : 2, "age" : 24, "name" : "shane"}]);
插入失敗,報如下錯誤:
2018-02-26T21:08:40.382+0800 E QUERY [main] TypeError: db.students.batchInsert is not a function :@(shell):1:1
原因:書中樣本batchInsert是按照version:2.4.0啟動並執行,到本版本已經廢棄該方法
解決方案:直接使用insert實現對students集合批量插入
db.students.insert([{"classid" : 1, "age" : 20, "name" : "kobe"}, {"classid" : 1, "age" : 23, "name" : "nash"}, {"classid" : 2, "age" : 18, "name" : "james"}, {"classid" : 2, "age" : 19, "name" : "wade"}, {"classid" : 2, "age" : 19, "name" : "bosh"}, {"classid" : 2, "age" : 25, "name" : "allen"}, {"classid" : 1, "age" : 19, "name" : "howard"}, {"classid" : 1, "age" : 22, "name" : "paul" }, {"classid" : 2, "age" : 24, "name" : "shane"}]); db.students.find()
控制台輸出如下,插入成功
